Abstract: L'invention concerne un procédé d'oxydation à basse température dans l'eau (ALTO) consistant à oxyder, à réduire et à rendre catalytiquement actif un catalyseur ou un précurseur catalytique composé d'un support solide, ou d'un composant en poudre, et d'un métal, ou d'un composant métallique, y compris de cobalt, afin d'effectuer des réactions d'hydrogénation du monoxyde de carbone. Le catalyseur ou le précurseur catalytique de cobalt est ainsi mis en contact avec un oxydant à basse température en présence d'eau (de l'eau dans laquelle l'oxydant est ajouté, par exemple), en quantité suffisante pour oxyder le cobalt ou le composant métallique du catalyseur ou du précurseur catalytique. Lors de la réduction, l'activité d'hydrogénation du catalyseur de cobalt augmente. Une partie ou l'ensemble du cobalt du précurseur catalytique est oxydé pour former des espèces cationiques ou oxoanioniques de Co¿2+? durant la phase initiale de la réaction au moins. Lors de la réduction, le métal ou le composant métallique catalytique du catalyseur est réduit à un métal métallique, comme, par exemple, du Co, et le catalyseur est ainsi activé, et/ou l'activité catalytique augmentée, comme cela peut être le cas par contact et traitement du catalyseur ou du précurseur catalytique oxydé avec de l'hydrogène ou un gaz contenant de l'hydrogène.

Patent CA-2422932-A1 (CA)
Inventor: MACKELVIE WINSTON R
IPC: F24H1/18
Filed: 2003-03-19
Abstract: A safety and energy saving improvement to a hot water heater whereby water can be heated to a high temperature (scalding hot) required for sanitizing and energy storage, but then is is internally cooled to a lower, non-scalding temperature before it leaves the heater. This is accomplished by means of a low-cost internal heat exchanger. In its simplest form, the internal heat exchanger is a vertically oriented tube structure one end of which is open to the hottest water at the top of the tank and the other end of which exits the tank. By sending the hottest water downwards through this tube, the hot water passes through the cooler layers of water in the tank and so gives up heat energy resulting in a lower water exit temperature. To maximize heat transfer where high storage temperature is preferred, the heat exchanger includes a larger outer sleeve which surrounds the vertical tube structure and into which sleeve the cold feed water is made to flow through the annular space therebetween. Also disclosed are means to automatically move the sleeve and/or deflect the cold water flow path to automatically vary heat transfer in response to the seasonal change of temperature of the cold feed water.

Filed: 2001-09-26
Abstract: A deflector for offsetting a streamer being towed by its lead-in by a seismic survey vessel comprises a wing-shaped body which is coupled to the lead-in and shaped to produce a sideways force which urges the lead-in laterally with respect to the direction of movement of the vessel. A boom extends rearwardly from the wing-shaped body, and forms part of an arrangement by which the angle of the wing-shaped body in the water, and therefore the sideways force produced by it, can be varied. The upper end of the wing-shaped body is directly connected to the underside of an elongate float.

Abstract: L'invention concerne un procédé d'adsorption modulée en pression permettant de séparer l'azote du gaz naturel, qui utilise deux étages séparés d'adsorption modulée en pression, le premier étage contenant un adsorbant sélectif vis-à-vis de l'azote. Dans ce procédé, le flux de produit provenant d'une première unité d'adsorption modulée en pression contient un flux de gaz naturel à contenu réduit en hydrocarbures, et le flux de produit provenant d'une seconde unité d'adsorption modulée en pression est un flux de gaz naturel à concentration réduite en azote. On utilise le produit provenant de la seconde unité d'adsorption modulée en pression pour désorber les hydrocarbures provenant de la première unité d'adsorption modulée en pression de façon à ajouter les hydrocarbures possédant un pouvoir calorifique au flux de gaz naturel. On a découvert que le chauffage périodique de l'adsorbant sélectif vis-à-vis de l'azote à l'aide du flux de produit chauffé provenant de la seconde unité d'adsorption modulée en pression augmente la capacité de l'adsorbant sélectif vis-à-vis de l'azote à adsorber ladite azote.

Abstract: A gas separation device (10) includes an inner conduit (14), and a concentri c outer conduit (18). An electrically conductive filter media (60), preferably  a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner  conduit and the annular space between the inner conduit and the outer condui t, so as to contact the filter media. The filter media preferentially adsorbs a t least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit are preferably electrically conductive whereby the  regeneration of the filter media can be electrically stimulated. The inventi on is particularly useful for the removal of CO2 from the exhaust gases of foss il- fueled power plants.
